If the sample did not have so much un-weathered material then yields of -45um fractions would be higher, and obviously what halloysite is in there would be greater.

Bear in mind that high grade halloysite is only generally found below 10m depth, so to get 15% halloysite at 3m is actually quite exceptional.
